// 如果已经引用过其他版本，wx 变量结果是 undefined
const wx = require('weixin-js-sdk')

// 正确写法
const wx = window.jWeixin || require('weixin-js-sdk')

如果是直接引入浏览器是不存在这个问题的
只有在 npm 多模块引用的情形下会形成我上面的结构
CommonJS 版本需要处理这个问题

由于代码里会判断 window.jWeixin
如果其他包里引用了其他版本的 weixin-js-sdk ，再次引用时 window.jWeixin 已经存在
导致代码逻辑不正确

既然代码里判断了 window.jWeixin，如果之前引入过其他版本的包，再次引入时就不会执行相关代码啊
